Most office supply stores sell laminators that you can use with your Student Attendance Cards.
For example, here is a Heat Seal Badge/Photo Laminator that is available at OfficeDepot.com
The link for this laminator is: http://www.officedepot.com/a/products/645270/GBC-HeatSeal-H110-ID-BadgePhoto-Laminator/
You will also need "pouches" that you can place the Studioware Student Attendance Card inside and heat seal. Again, most office supply stores sell the laminating pouches. Here are two sets of pouches that are available from OfficeDepot.com
This is a pack of 25 pouches. The link for these pouches is http://www.officedepot.com/a/products/535616/Office-Depot-Clear-Laminating-Pouches-ID/
We recommend getting the 5 Mil thick pouches to ensure that the barcode can be scanned through the plastic coating.
